`IIIJQUIll)-MFiASURINGr AND REGISTERING DEVICE.

Specification of Letters Patent. l Patented Apr. 30, 1918.

Application led August 11, 1915. Serial No. 45,028.

To all whom it may concern:

Be it known that I, NICHOLAS HERMANN STENECK, a citizen of the United States, and residing at Hoboken, in the county of Hudson and State of New Jersey, have invented certain new and useful Improvements in Liquid-Measuring and Registering Devices, of which the following is a clear and concise specification, reference being had to the accompanying drawings, forming a part of this specification.

This invention relates to registering devices.

One object of the invention is to provide a liquid measuring and registering device, being comparatively simple of construction and to be readily attached to a liquid holding tank.

Another object of the invention resides in the provision of means to register automatically the quantity of liquid deposited from time to time in the vessel to which the device is attached.

A still further object -of the present invention resides in the fprovision of means to prevent the device rom registering at times other than when filling the tank or container. I

It is still further designed to provide a liquid measuring and registering device Awhich is readily and etiicient to use and dependable at all times and which is not operatable through any other meansl except through the introductionof liquid into the vessel, tank or container to which the device is attached.

It is still further designed to provide a liquid measuring and registering device in which the registering means are prevented from operation through possible outside iniuences.

With the above and other objects in view, the invention consists in the construction and novel combination of parts, hereinafter fully described, illustrated in the accompanying drawing, and ointed outin the claims appended hereto, it being understood, that various changes in the form, proportion, size, arrangement and minor details of construction, may be resorted to without departing from the s iritor sacrificing any of the advantages o the invention.

In the drawings:

Figure 1 is a sectional view through a liquid lcontaining vessel, as for instance an automobile gasolene tank or the like and Fig. 4 is a sectional view through the filler .vent and cap, showing more precisely the method of operating the valve mechanism.

Fig. 5 is a sectional view through the valve chamber and connecting ni ple, showing more clearly the path of the iquid and the operation of the valve and brake, and

f Fig. 6 is a sectional view along the line B-B of Fig. 5.

Referring now more particularly to the drawings, character 7 indicates a liquid containing tank, such as is used on motor vehicles and the like and provided with a filling vent 8 being threaded to engage with the thread of a cap 9, to securely close said vent.

Secured to one side of the tank 7 in any convenient manner, preferably through means of flanged bushing 10, is the measuring and recording chamber 11, being of any desired form or shape, preferably cylindrical and provided with a ni le 12, threaded so as to engage the thread o the bushing 10.

Measuring and registering chamber 11 is provided at the center of its upper and lower covers with suitable bearings 13 and 14 to receive a spirally grooved or threaded shaft 15. The spiral groove or thread of the shaft being of varyin pitch determined b. ,the shape of tank that is for tanks w ose vertical sections are not rectangular, the pitch is such that the rotation of the shaft is in direct proportion to the volume as indicated by the level of the liquid in the tank 7. A gear 16 is keyed to one end of the aforesaid shaft 15, engaging the pinion 17, which latter is provided at lthe upper end with ratchetteeth, normally held in engagement with corresponding teeth on the actuating shaft 18 of a suitable register 19,by .means of spring 20.

Movably mounted on the grooved shaft 15 is a float 21, carrying a suitable element adapted to engage the thread or groove of shaft 15, so that when said fioat is raised by the increasing height of the liquid, it will rotate the shaft 15, since the ioat itself is restrained from rotation.

The gear 16 being keyed to the aforesaid shaft 15 and normally in mesh with pinion 17, will when rotated through the pinion 17 actuate the register 19.

In order to prevent the possibility of registering at any other. time than when refilling the tank, the registering chamber 11 1s provided with a valve. lln order to guide the valve stem 23 and disk 22, a member 24 threaded to engage similar threads on the nipple 12 is provided. rllhe bearing support 2.' of member 24 is provided with holes 25 to permit theiow of liquid to the valve chamber 26.

The aforesaid bearing support 27 serving also as a seat for the valve spring 28. One end of the valve stern 23 terminates in a fork 29, adapted to engage the shaft 15 and prevent its rotation when the valve is closed. The opposite end of the valve stem 23 is provided with a disk 30 forming a contact surface for the nose of the lever 3l and also as a retainer for the valve spring 28.

The valve operating lever 31 is pivoted to the supporting member 32 through means of a pin 0r the like' 33. r1`his supporting member 32 consists preferably of a cylindrical body portion provided with a thread engaging the external thread of member 24 and arms 32, 32,so arranged that the disk 30 can pass freely through the bight of said arms. .l

The pin 34 is provided to limit the upward movement of the valveA lever 31. A rod 35 terminating in a fork 36 at its lower nd is slidably held in a bearing 37 at its upper end. Rim 38 on cap 9 is provided for the tpurpose of depressing rod 35 and also sealing the bearing 37 so as to prevent possible leakage of the liquid contained in the tank 7.

Reference to the aforesaid drawings` clearly indicate, that removal of the cap 9 uncovers vent 8 and bearing 37, permitting rod 35 to move upward', since spring 28 bearing on disk 39 imparts a'pressure on the nose of the lever 31 and thereby pressing said lever upward and in turn therod 35 to a position such as is permitted by the stop pin 34. In this position of the mechanism more clearly indicated by Fig. 5, the valve stem 23 -having been moved laterally by the expansion of spring 28, disengaging the spiral threaded or grooved shaft 15 and the forky 29 and opening the valve; the How of liquid is then permitted into the measuring and registering chamber 11 in which it wi l reach a level predetermined by the level in tank 7,

rlhe vertically guided oat 21 when moving downward with the liquid in the chamber 11 causes a rotation of the shaft 15 in such a direction as to disengage the ratchet from pinion 17 and shaft 18, thus preventing the rotation of shaft 18; when moving upward the float 21 causes the shaft 15 to rotate in such a direction, that the gear 16 in mesh with pinion 17 permits the normal engagement of the ratchet teeth of pinion 17 and Shaft 18 due to the spring 20 and consequently rotates shaft 18 and register 19.

The liquid deposited in the tank 7through vent 8 raises the level in tank 7 and the passage of liquid through holes 25 of the valve and into thev measuring and registering chamber 11 causes an equal rise in said chamber 11.

Since the rising level in the tank causes the float 21 to rise also the actual rise of liquid is faithfully recorded onthe register dial and thereby registering the true volume of liquid deposited in tank 7.

Having thus described my invention what I claim as new and desire to have protected by Letters Patent is:

In a device of the character described, a tank provided with a vent, a closure for the vent, a float chamber provided with a float and al register and communicating with the tank and also provided with an operating shaft for the register, said shaft having connection with said float, a valved communication between the tank and float chamber and means for governing the operation of the valve and also for governing the operation of said shaft upon the opening ing of the vent closure so as to operate the register.

2. In a device of the class described, a tank provided with avent, a closure for said vent, a float chamber communicating with the tank by means of a passage and provided with a register, and means operated by the opening or closing of the vent closure for opening or closing said aage and also governin the operation ofpthe register.
